    On March 17-18, 2010, Prof. Tony Atkins from the University of Reading UK visited LNM, IMECH CAS.

    Tony Atkins is a fellow of the Royal Academy of Engineering UK. He is Professor Emeritus of Mechanical Engineering at the University of Reading. He came to Reading from industry (Delta Group). Before that he had taught at the University of Michigan and the University of Oxford. He is a chartered Engineer working in the field of large deformation flow and fracture of all sorts of materials. His particular interest is the interplay of macro and micro aspects. Applications have been to a variety of materials including metals, alloys, plastics, composites, ice and biological materials. He has written over two hundred papers published in referred learned journals and is the co-author of many books.

    On March 17, Prof. Atkins gave a wonderful lecture on “The Science & Engineering of Cutting”. His lecture showed how cutting is all around us, not only in engineering science, but also in biology, medicine, food technology, arms and amour, and so on. Prof. Atkins gave many impressive examples from all these, and others, fields along with how the process are modeled and analyzed, how a better understanding of cutting mechanics can improve applications in these fields. In the second morning, Prof. Atkins gave a more detailed lecture entitled as “Toughness and Processes of Material Removal”. He discussed firstly how to estimate the forces for brittle chipping using elastic fracture mechanics. Then, he presented how to estimate the forces and the toughness energy for ductile cutting. Prof. Atkins argued that cutting is a branch of fracture mechanics, even though “you don’t see cracks at the tip of the tool in continuous chip cutting of ductile materials”. Finally, Prof. Atkins discussed thoroughly with some researchers and students in LNM.
